Sorry for being late on this everybody!
So pretty much I called the original manufacturer in Cali that was once Signtronix, They brought up the original order from 2001 and forwarded me to the local sales rep. Apparently they have distribution across the USA to other shops for their signs.
They didn't want to sell wholesale and told me they could remake these from pan to art applied for $2300...Yeah I can't make anything on that.
The rep wouldn't tell me how thick they originally made them but as you can see, I'm not THAT crazy on stating they are as thin and I said. See the photos.
There's literally zero room in the cabinet because I had to fight pretty hard to get them even out. I called 3 pan face manufacturers and nobody can make this sign pan under .150 thick. I even had one guy who's done pan faces for 29 years tell me he can't believe even the photos lol
Monday I'm going to go to the customer who had this job and a few others which we already did just to be honest about not being able to complete it. Sucks but I don't have the know how to modify the cabinet to fit something thicker.
Appreciate you guys' help
